HOT-AIR REGISTER.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application iiiea April 20,1906. serial No. 312,853.

To all whom it may concern:

Be it known that we, SAXTON J. MORGAN and HAR- RIS M. WHIToouB, citizens of the United States, residing at Albany, in the county of Green and State of Wisconsin, have invented a new and useful Hot-Air Register, of which the following is a specification.

This invention relates to hot air registers and its object is to provide a device of this character constructed solely of sheet metal, which is formed of very few parts, which does not necessitate the employment of rivets or other similar fastening means and the parts of which are securely bound together so as to present a compact and durable structure.

With the above and other objects in view the invention consists of a frame formed of stripssecured together in a novel manner and the side. strips constitute bearings for the trunnions of metallic slats each slat and its trunnions being formed in a single sheet of metal and having an integral arm engaging an actuating slide mounted on one of the side strips.

The invention also consists of certain other novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the prep ferred form of the invention.

In said drawings: Figure l is a perspective view of the device; Fig. 2 is a transverse section therethrough showing, by dotted lines, the positions of the -parts when open; Fig. 3 is a section through one of the sides of the device; and Fig. 4 is a detail view of one end of a slat.

Referring to the figures by numerals of reference, 1 and 2 are side strips each having a channel 3 in its outer face along one edge forming an inwardly extending bead 4 having a plurality of circular openings 5 therein. Inwardly extending flanges 6 are formed longitudinally along the other edge of each side strip. An vend strip 7 is mounted on the side strips and has end llanges'S which overlap the side strips and also has longitudinally extending side flanges 9 and 10, the flange 9 being disposed between the beads 4 whereas the flange l() terminates in right angle extensions ll which overlap the side strips just above their flanges 6. The flange l() is bent inward throughout its length with the exception of the end portions thereof where it is formed with openings 12 to receive bolts or other means for securing the frame to the floor or other supporting structure. The extensions ll and end flanges 8 are fastened to the side strips by punching holes through said side strips, flanges and extensions causing the metal of the side strips to project through the flanges and extensions whereupon said metal is upset so as to answer every purpose of a rivet. This means for fastening the parts is clearly illustrated at 13. The

other end strip 14 of the frame is exactly similar to the strip 7 `and is fastened to the side strips in the same manner as described in connection with the strip 7.

Interposed between the side strips are a plurality of metal slats l5 each of which is formed of sheet metal and has a central longitudinally extending channel 16 therein at the ends of which are formed tubular trunnions 17 each trunnion being produced by wings 1S which are formed integral with the ends of the slat and are bent into cylindrical form. At one end of each slat at a point removed from the adjoining trunnion is an integral arm 19 extending at right angles from the slat and folded longitudinally upon itself so as to bring together two semi-cylindrical parts 20 to produce a cylindrical arm extending at right angles from the arm 19. One of these upstanding arms 20 is formed with each slat l5 and each of said arms projects into one of a series of slots 2l disposed transversely in a channeled strip 22. This strip is slidably mounted on the inner face of one of the side strips between the bead 4 and the flange 6 thereof said flange being bent inward for a portion of its length as shown at 23 for the purpose of overlapping the strip 22 to retain it in position on the side strip and at the same time permit it to slide.

A U-shaped grip 24 is mounted on the exposed face of a sliding strip 22 and has lateral extensions 25 which extend through slots 26 in the sliding strip and are secured therein by upsetting their ends. A

When it is desired to open the register box the grip 24 is moved longitudinally of the side of the frame and the slide 22 is carried therewith. Said slide will therefore transmit an upward swinging movement to the arm 19 and cause all of the 4slats to swing upon their trunnions. The grip 24 is so positioned that when each slat has moved about 90D one of the slats will swing into contact therewith. All of the slats will thus be held in opened position. To close the slats the movement of the grip and slide is reversed and the two end slats will thus be swung into contact with the flanges 9 of the end sections.

It is to be noted that where a register box is provided with four slats the entire box consists of but ten pieces, to wit; the four slats, the four members of the frame, the slide and the grip and every part of the frame is constructed of sheet metal which may be readily stamped into shape. The device can therefore be constructed at 'comparatively slight cost and because of its compact and simple construction will be found to be very durable. Considerable importance is attached to the novel means for fastening the corners of the frame together simply by punching the metal of two overlapping parts and upsetting the displaced metal so as to firmly bind said parts together. With this construction the use of grips is dispensed with and the parts are fastened together with as much security as though rivets Were employed. It is of course to be understood that if preferred rivets may be used.

Vhat is claimed is:

1. A hot air register comprising a frame having inwardly extending beads on the sides thereof and an inturned llange on one of said sides, slats mounted to rotate between the beads, arms extending from the slats, a slide engaging said arms, said slide being retained upon one of the sides by said inturned ilange, and a grip upon the slide, said grip constitutingr a stop for the slats.

2. A hot air register comprising a frame the sides thereof having inwardly extending beads, and one of said sides having an inturned flange, a slide retained upon said side by the inturned flange, said slide being slotted, normally overlapping slats interposed between the sides, said slats having trunnions rotatably mounted Within the beads, arms seated in the slots in the slide, and a grip extending from the slide and constituting a stop for the slats.

A hot air register comprising a frame, slats mounted to rotate Within the frame, arms extending from the slats, a slide engaging the arms, means for retaining the slide upon one of the sides of the frame, and a grip upon the A.slide and constituting a stop for the slats.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures in the presence of two witnesses.
